## Summary description

The BlueOptics 02311KNW is a 1 m InfiniBand fibre optic cable with QSFP28 connectors. Designed for high-speed data transmission, it features male connectors on both ends, ensuring reliable connectivity for data centers and high-performance computing environments.

## Long description

The BlueOptics 02311KNW InfiniBand fibre optic cable 1 m QSFP28 Male/Male is a short, single-length high-speed connectivity solution intended for data centres and high-performance computing environments. It uses QSFP28 male connectors on both ends and is engineered to support the InfiniBand protocol over optical fibre, providing low latency and high bandwidth over a one-metre link.
Advantages
This 1 m InfiniBand fibre cable offers compact, direct connectivity between QSFP28 ports with minimal signal loss and consistent optical performance. Its male-to-male QSFP28 terminations simplify port-to-port connections without additional adapters. The cable is suitable for rack-level interconnects where short, reliable optical links are required and is designed to maintain stable data transmission for demanding applications.
Suitable for
Short-distance interconnects in data centres
High-performance computing clusters and node-to-switch links
Server-to-switch connections in rack deployments
Low-latency storage networking and InfiniBand fabrics
Key specifications
Cable type: InfiniBand multimode fibre optic cable
Connector type: QSFP28 male to QSFP28 male
Length: 1 metre
Designed use: Short-reach, high-bandwidth optical interconnects
Performance characteristics: Low latency, high data throughput suitable for InfiniBand networks
How to use
Inspect both QSFP28 connectors and the fibre ends for cleanliness before installation. Align each QSFP28 male connector with the corresponding QSFP28 port on devices such as switches, NICs or host channel adapters and insert firmly until the connector latches. Ensure cable routing avoids sharp bends and excessive tension; maintain the manufacturer-recommended bend radius for multimode fibre. For removal, disengage the connector latch before pulling the plug straight out to avoid damaging the port or fibre.
Usage recommendations
Use with compatible QSFP28 ports and InfiniBand-capable network equipment. Clean connectors with appropriate fibre cleaning tools and follow data centre cable management practices to preserve signal integrity. For optimal performance, keep the cable length appropriate to the deployment and avoid coiling tightly or subjecting the cable to mechanical stress.
